hello guys!! someone is running with 3" exhaust in n/a??
I run 3" straight pipe and headers on my 12v and it hasnt lost any hp or torque in fact in the 12v fourm there is a back to back dyno of a 2.5" to 3" and it made more hp and tq and thats on a 2.8 so that being said on a vr6 bigger is better and its been proven. Ill post it in here if there is any more debate.
